This is an unfair puzzle because there's no way to know that G5 is en passant.

Black's last move could only have been ...g7-g5. His other pawns have never moved, and any of his pieces could only have moved from squares where White pieces are now sitting. The g-pawn couldn't have come from g6 where it would have been checking the White king, and could not have come from f6/h6 with a capture. Hence ...g7-g5 is the only possible move, and the en passant capture is possible.

There are many puzzles like this in GK, I remember two of them, made by great masters, we there are very few pieces on the board but you still have the possibility to castle. I agree it´s unfair but this trick have been widely used.

I retract my comment -- definitely a puzzle, and a good one!

Hats Off!

Hence ...g7-g5 is the only possible move, and the en passant capture is possible.[/i]

Precisely!!! Not only is it not 'unfair' - like the castling puzzles - but the e.p. capture makes this a rich puzzle!!! Congrats and hats off!

Solving this successfully has really inspired me.

Not correct

Blacks last move could have been bxa1 and promotion to Knight,

Opinion changed yet agiain

First I didn't like it, because how would you know white could take e.p? Then I read the comments and realised, its quite a good puzzle. But then I read the comment above, now I don't know what to think...

Puzzle 5957

It looks to me as though B x g5 is also Mate?? (in 2)

sjaak123, black couldn't have promoted to a knight on a1, it would have to be b1.

miledout, I'm afraid not, knight checks on e7

pawn takes a piece f.e rook on a1

Corrigendum

A white pawn on b2 would make this puzzle complete. As you people pointed out, the last black move could have been bxa1=N (capturing the only missing white piece, a knight).

And Bxg5 is met by Nf6 ...

1.Bxg5 is not mate in two because of 1... Sf6 and not because of 1...Sxe7+ 2.Dxe7 mate

place a white pawn on b2 and it's complete. Cute idea though. Props.

Impossible!

The last move could not have been bxa1=N because that's black's side!!!! A pawn can not move backwards!

correction

that should be cxb1

sjaak123

cmethan, why backwards: maybe for a complete description:

the last move for black: black pawn on b2 takes a white piece (rook) on a1 and promotes to knight.

not legal...

This is an unfair puzzle because there's no way to know that pawn g5 creates an en passant move...!

sjaak123, you are correct.

It's certainly captious...

Because you have to 'IMAGINE' last black move providing en passant capture.

Points taken

Thanks for the nice comments, from those who enjoyed my puzzle. And sjaak123, you are correct that the last move could have been ...bxa1=N (as strange as that move would be). Simply adding a white pawn on b2 would fix it, but alas... I can't do that. (Edits can only be made to the description.) I will have to delete this puzzle and create a new one, unfortunately.

Don't delete, just add a new one.

Proliferation, seems to be the way here. But a better argument is that when solving puzzles, and you hit a similar one 3 weeks (or whatever) after solving the original it reinforces whatever it is that you learned the first time.

I solved it by clicking on every piece first to see where he could move

Agree.

thebish, I said puzzle is captious: But it is really GREAT ! And legal. In a correct chess position. A very nice brain creation !

Maybe another small fix?

Add white a rook and knight somewhere on the board.
With those two pieces still around, bxa1 would also be impossible, because all pieces are accounted for.

Its does the trick too, but harder to figure out then adding a pawn on b2.
Howabaout adding Rh1 and Nb1?
